Ukuskena iilensizisetyenziswa kakhulu kwi-AOI, ukuhlola ushicilelo, ukuhlolwa kwelaphu elingalukwanga, ukuhlolwa kwesikhumba, ukuhlola umzila kaloliwe, ukuhlola kunye nokuhlela imibala kunye namanye amashishini.Eli nqaku lizisa intshayelelo kwiilensi zokuskena kumgca.

Intshayelelo kwiLensi yokuSkena kumgca

1) Ingqikelelo yelensi yokuskena umgca:

I-lens ye-CCD ye-line ye-lens yi-FA ye-lens ephezulu ye-lens ye-line sensor series cameras ehambelana nobukhulu bomfanekiso, ubungakanani be-pixel, kwaye ingasetyenziselwa uhlolo oluchanekileyo oluphezulu.

2) Iimpawu zelensi yokuskena umgca:

1. Yenzelwe ngokukodwa izicelo zokuskena eziphezulu, ukuya kuthi ga kwi-12K;

2. Eyona ndawo iphezulu yokujonga umfanekiso ohambelanayo yi-90mm, kusetyenziswa ikhamera yokuskena umgca omde;

3. Isisombululo esiphezulu, ubuncinane be-pixel ubukhulu ukuya kwi-5um;

4. Izinga lokugqwesa eliphantsi;

5. Ukwandiswa 0.2x-2.0x.

Iingqwalasela zokuKhetha iLensi yokuSkena ngomgca

Kutheni le nto kufuneka sicinge ngokukhetha iilensi xa sikhetha ikhamera?Iikhamera eziqhelekileyo zokuskena okwangoku zinezisombululo ze-1K, 2K, 4K, 6K, 7K, 8K, kunye ne-12K, kunye nobukhulu bepixel ye-5um, 7um, 10um, kunye ne-14um, ukuze ubukhulu be-chip bususe kwi-10.240mm (1Kx10um) ukuba 86.016mm (12Kx7um) iyahluka.

Ngokucacileyo, i-interface ye-C ikude ukuhlangabezana neemfuno, kuba i-interface ye-C inokudibanisa kuphela ii-chips ezinobungakanani obukhulu be-22mm, oko kukuthi i-intshi eyi-1.3.I-interface yeekhamera ezininzi ngu-F, M42X1, M72X0.75, njl. Ujongano lwe-lens oluhlukeneyo luhambelana nokugxilwa komqolo ohlukeneyo (umgama we-Flange), omisela umgama wokusebenza we-lens.

1) Ukwandiswa kwamehlo (β, Ukwandiswa)

Nje ukuba isisombululo sekhamera kunye nobungakanani bepixel bumiselwe, ubungakanani boluvo bungabalwa;ubungakanani boluvo olwahlulwe ngomhlaba wemboniselo(FOV) ilingana nokwandiswa kokubona.β=CCD/FOV

2) Ujongano (Intaba)

Kukho ubukhulu becala C, M42x1, F, T2, Leica, M72x0.75, njl. Emva kokuqinisekisa, unokwazi ubude be-interface ehambelanayo.

3) Umgama weFlange

Ujoliso lwangasemva lubhekiselele kumgama ukusuka kwinqwelomoya yojongano lwekhamera ukuya kwitshiphu.Yiparameter ebaluleke kakhulu kwaye igqitywe ngumenzi wekhamera ngokwendlela yayo yokuyila.Iikhamera ezivela kubavelisi abahlukeneyo, kunye ne-interface efanayo, zinokuba nokugxila okwahlukileyo ngasemva.

4) MTF

Ngokwandiswa kwe-optical, i-interface, kunye nokugxila ngasemva, umgama wokusebenza kunye nobude bendandatho edibeneyo ingabalwa.Emva kokukhetha ezi, kukho enye ikhonkco ebalulekileyo, kukubona ukuba ixabiso le-MTF lilungile ngokwaneleyo?Iinjineli ezininzi ezibonakalayo aziyiqondi i-MTF, kodwa kwiilensi eziphezulu, i-MTF kufuneka isetyenziswe ukulinganisa umgangatho wokukhanya.

I-MTF igubungela ubutyebi bolwazi olufana nochasaniso, ukusonjululwa, ukuphindaphindeka kwendawo, ukuphambuka kwechromatic, njl.njl., kwaye ibonakalisa umgangatho wokubonwa kweziko kunye nomphetho welensi ngokweenkcukacha ezinkulu.Akukona nje kuphela umgama wokusebenza kunye nommandla wokujonga uhlangabezana neemfuno, kodwa ukuchasana kwemiphetho akulunganga ngokwaneleyo, kodwa nokuba ngaba ukukhetha i-lens yesisombululo esiphezulu kufuneka kuqwalaselwe kwakhona.
